Priority-Based Channel Occupancy in Shared Wireless Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, overlapping resources during scheduled transmissions can interfere with each other, leading to inefficiencies and potential collisions, especially when multiple user equipment (UE) attempt to access shared channel resources simultaneously.
Innovation Solution
Implementing a method where user equipment determine a transmission priority for shared channel resources and compare it to a threshold priority, initiating channel occupancy only if the priority exceeds the threshold, thereby preventing unnecessary channel access and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple user equipment attempt to access shared channel resources simultaneously, then channel utilization increases, but interference and collisions increase
Solution Approach 1:
The patent changes the parameter of channel access by introducing priority levels and threshold comparisons. User equipment determines a transmission priority for each transmission and compares it to a threshold priority, initiating channel occupancy only when the priority exceeds the threshold. This parameter-based control mechanism allows the system to dynamically adjust channel access behavior based on transmission importance, thereby maintaining high channel utilization for critical transmissions while preventing unnecessary access that would cause interference and collisions.
2Productivity
If user equipment initiates channel occupancy for all transmissions, then transmission opportunities increase, but interference with other transmissions increases
Solution Approach 1:
The patent applies local quality by differentiating channel access behavior based on the specific characteristics of each transmission. Instead of a uniform access policy, each transmission is evaluated individually with its own priority level. The user equipment determines a transmission priority specific to each transmission and compares it locally against the threshold, initiating channel occupancy only for those transmissions that meet the priority criterion. This localized decision-making ensures that only transmissions with sufficient importance generate channel occupancy, reducing overall interference while preserving opportunities for critical data.
3Reliability
If user equipment compares transmission priority to threshold and initiates occupancy only when priority exceeds threshold, then interference is reduced, but some transmission opportunities are lost
Solution Approach 1:
The patent utilizes parameter changes by dynamically adjusting the threshold priority level based on channel conditions and transmission requirements. The threshold is not fixed but can be modified to balance reliability and delay requirements. When channel conditions are favorable or transmission priority is critical, the threshold can be raised to ensure only high-quality access attempts occur, improving reliability. Conversely, when latency is critical or channel conditions deteriorate, the threshold can be lowered to prevent excessive transmission delays, thus dynamically optimizing the trade-off between reliability and time loss.
